NASA - National Aeronautics and Space AdministrationPasadena, CA – A view from NASA’s Mars Reconnaissance Orbiter on April 8th, 2015, catches sight of NASA’s Curiosity Mars rover passing through a valley called “Artist’s Drive” on the lower slope of Mount Sharp.

The image from the orbiter’s High Resolution Imaging Science Experiment (HiRISE) camera shows the rover’s position after a drive of about 75 feet (23 meters) during the 949th Martian day, or sol, of the rover’s work on Mars.

NASA’s Mars Reconnaissance Orbiter spots Beagle 2 Mars Lander that’s been lost on Mars since 2003

NASA - National Aeronautics and Space AdministrationPasadena, CA – The Beagle 2 Mars Lander, built by the United Kingdom, has been thought lost on Mars since 2003, but has now been found in images from NASA’s Mars Reconnaissance Orbiter.

A set of three observations with the orbiter’s High Resolution Imaging Science Experiment (HiRISE) camera shows Beagle 2 partially deployed on the surface of the planet, ending the mystery of what happened to the mission more than a decade ago. They show that the lander survived its December 25th, 2003, touchdown enough to at least partially deploy its solar arrays.

This annotated image shows where features seen in an observation by NASA's Mars Reconnaissance Orbiter have been interpreted as hardware from the Dec. 25, 2003, arrival at Mars of the United Kingdom's Beagle 2 Lander. The image was taken in 2014 by the orbiter's HiRISE camera.

NASA researchers discover dusty star system similar to our solar system

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Researchers studying what appears to be a beefed-up version of our solar system have discovered that it is encased in a halo of fine dust. The findings are based on infrared data from NASA’s Spitzer Space Telescope and the European Space Agency’s Herschel Space Observatory, in which NASA is a partner.

The dusty star system, called HD 95086, is located 295 light-years from Earth in the constellation Carina. It is thought to include two belts of dust, which lie within the newfound outer dust halo.

This artist's concept depicts giant planets circling between belts of dust. Scientists think the star system HD 95068 may have a planetary architecture similar to this. While the star system's two dust belts are known, along with one massive planet, more giant planets may lurk unseen. (NASA/JPL-Caltech)

NASA’s Dawn Mission creates Geological Maps of Asteroid Vesta

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Images from NASA’s Dawn Mission have been used to create a series of high-resolution geological maps of the large asteroid Vesta, revealing the variety of surface features in unprecedented detail. These maps are included with a series of 11 scientific papers published this week in a special issue of the journal Icarus.

Geological mapping is a technique used to derive the geologic history of a planetary object from detailed analysis of surface morphology, topography, color and brightness information.

NASA’s Cassini Mission data reveals Jupiter’s Red Spot probably created by Chemical reaction to Sunlight

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The ruddy color of Jupiter’s Great Red Spot is likely a product of simple chemicals being broken apart by sunlight in the planet’s upper atmosphere, according to a new analysis of data from NASA’s Cassini mission. The results contradict the other leading theory for the origin of the spot’s striking color — that the reddish chemicals come from beneath Jupiter’s clouds.

The results are being presented this week by Kevin Baines, a Cassini team scientist based at NASA’s Jet Propulsion Laboratory, Pasadena, California, at the American Astronomical Society’s Division for Planetary Science Meeting in Tucson, Arizona.

Research suggests effects of sunlight produce the color of Jupiter's Great Red Spot. The feature's clouds are much higher than those elsewhere on the planet, and its vortex nature confines the reddish particles once they form. (NASA/JPL-Caltech/ Space Science Institute)

NASA’s Cassini spacecraft finds two new features about Saturn’s moon Titan’s Hydrocarbon Seas

 

Written by Preston Dyches
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Cassini mission continues its adventures in extraterrestrial oceanography with new findings about the hydrocarbon seas on Saturn’s moon Titan.

During a flyby in August, the spacecraft sounded the depths near the mouth of a flooded river valley and observed new, bright features in the seas that might be related to the mysterious feature that researchers dubbed the “magic island.”

The findings are being presented this week at the Division for Planetary Sciences Meeting of the American Astronomical Society held in Tucson, Arizona.

NASA’s Mars Curiosity Rover confirms first Mineral Mapped from Space

 

Written by Preston Dyches and Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Reddish rock powder from the first hole drilled into a Martian mountain by NASA’s Curiosity rover has yielded the mission’s first confirmation of a mineral mapped from orbit.

“This connects us with the mineral identifications from orbit, which can now help guide our investigations as we climb the slope and test hypotheses derived from the orbital mapping,” said Curiosity Project Scientist John Grotzinger, of the California Institute of Technology in Pasadena.

This image shows the first holes drilled by NASA's Mars rover Curiosity at Mount Sharp. The loose material near the drill holes is drill tailings and an accumulation of dust that slid down the rock during drilling. (NASA/JPL-Caltech/MSSS)

NASA’s Cassini spacecraft takes photo of sunlight reflecting off the seas on Saturn’s moon Titan

NASA - National Aeronautics and Space AdministrationPasadena, CA – As it soared past Saturn’s large moon Titan recently, NASA’s Cassini spacecraft caught a glimpse of bright sunlight reflecting off hydrocarbon seas.

In the past, Cassini had captured, separately, views of the polar seas and the sun glinting off them, but this is the first time both have been seen together in the same view.

NASA’s Opportunity Rover takes picture of ‘Wdowiak Ridge’ on Mars

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The latest fieldwork site for NASA’s Mars Exploration Rover Opportunity, which has been examining a series of Martian craters since 2004, is on the slope of a prominent hill jutting out of the rim of a large crater and bearing its own much smaller crater. It’s called “Wdowiak Ridge.”

“Wdowiak Ridge sticks out like a sore thumb. We want to understand why this ridge is located off the primary rim of Endeavour Crater and how it fits into the geologic story of this region,” said Opportunity science-team member Jim Rice of the Planetary Science Institute, Tucson, Arizona.

This vista from NASA's Mars Exploration Rover Opportunity shows "Wdowiak Ridge," from left foreground to center, as part of a northward look with the rover's tracks visible at right. (NASA/JPL-Caltech/Cornell Univ./Arizona State Univ)

NASA’s Mars Reconnaissance Orbiter discovers evidence that Gullies on Mars are being created by Dry Ice

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Repeated high-resolution observations made by NASA’s Mars Reconnaissance Orbiter (MRO) indicate the gullies on Mars’ surface are primarily formed by the seasonal freezing of carbon dioxide, not liquid water.

The first reports of formative gullies on Mars in 2000 generated excitement and headlines because they suggested the presence of liquid water on the Red Planet, the eroding action of which forms gullies here on Earth.

This pair of images covers one of the hundreds of sites on Mars where researchers have repeatedly used the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter to study changes in gullies on slopes. (NASA/JPL-Caltech/Univ. of Arizona)
